Red

He finished public elementary school and then immediately disappeared for the mountains. Literally living my dream.

What else does he need.

Blue

Continued schooling at a private high-school while being a gym leader, then went to uni in Kalos to be a Pokémon professor.

Lance

Homeschooled from elementary to high school by his dragon clan. Then went to a private prestigious university in Galar (The same one Cynthia and Steven would eventually go to.)

Wallace

(He counts, he's the champion of my heart)

Secular Private school kid, all his life. (like meeee) Probably didn't go to university in favor of Contests, since he blew up in popularity around his mid teens.

Steven

Rich kid, private elementary school, private international school abroad and then abroad again to a uni in Galar. (all non secular)

Cynthia

Her family is rich but not that rich, Public elementary school and then secular private high school. Then obviously abroad in Galar.

Alder!!

I imagine a small schoolhouse for him in Floccessy town, where he schooled for elementary where his mom taught at. I don't think he got any higher schooling than that because I headcannon he went on his Pokémon journey on his teens and kept the title of champion for a long while.

N

(If I'm counting Wallace I'm counting him too)

Homeschooled.

Actually homeschooling is an overstatement. He learned maths, of course. Ghetsis probably found out he was a genius in maths and fed into it because he thought it would be useful for later.

Then how to read and write, some basic words and simple things and then the rest was just blatant propaganda to brainwash N into thinking all Pokémon trainers suck.

Iris!!!

She reeks of homeschooled kid whose spark hasn't been crushed by bullies. A very outdoorsy girl who goes out to play, do her workbooks for an hour and then pop out to play or train even more.

For high-school though I think she'd attend Blueberry academy.

Diantha

I'm not saying she's a nepo baby, but she is a non-secular private school kid who went to Uni in Kalos.

Professor Kukui

Public Elementary school, Public highschool, scholarship to a fancy schmancy private university.

Leon.

Hear me out:

ACE kid.

He became champion really young so he probably didnt go to normal school as a kid, so ACE it was. He was enrolled there, but he never really showed up except if you counted him coming in once a month to get his Paces and pace tests

For the uninformed, Ace is a school system focused on self learning.

They give you a short workbook called a PACE that is essentially a week or twos worth of lessons, a goal chart that you have to set yourself which is basically a little calendar where you write your goal page, usually 3 - 5 pages and then you finish it at the end of the day.

If you are ever done with a goal or page, you go to the scoring station and then score it yourself.

Once you're done, you immediately take a test for all the stuff you learned.

That's basically the gist of it, but Leon would do his Paces in between training sessions, once the week was over, the finished paces and pace tests would go to the teacher to be graded.

Geeta

She went to Naranja/Uva and it kinda strikes me as a good private school with functioning bathrooms so we'll go with that.
